SubFree is a free and simple subdomain service inspired by is-a.dev, designed for developers, creators, and builders who want custom subdomains — without touching complex code, repos, or GitHub forks. Just request a subdomain through the web app, and it’s automatically managed through Cloudflare. Fast, secure, and stress-free.
- No complex repositories — no forks or JSON edits, just a clean web interface.
- Captcha protection — to keep spam and bots out.
- Smart validation — ensures subdomains are clean, valid, and conflict-free.
- Automatic DNS updates — your subdomain goes live right after approval.
- Fast API — efficient backend support for all processes.
You can use SubFree with any public project hosted on platforms like:
